问题
I've used AudioKit.inputDevice, Audiotkit.outputDevice, and friends to get get all input and output devices on my Mac, and to get/set default input and output device.
I wish to read the current volume of these devices, and to be able to set it myself, but I can't find the correct AudioKit API for doing so.
Does anyone know how to do this?

You will want to use a library similar to https://github.com/InerziaSoft/ISSoundAdditions
Changing sound volume becomes as simple as:
[NSSound setSystemVolume:0.5]
